CEDAR WORMS. 919 



attached to the twigs of the tree, can not be mistaken for anything else. 

 Many of these contain the eggs, which remain throughout the winter 

 and hatch in the following May. They may consequently be removed 

 and destroyed by hand in the winter and spring, or the trees may be 

 protected by spraying with Paris green or other similar poison in June 

 or July, when the worms are eating the leaves. (Forbes' First Report 

 Ins. Illinois.) 



3. Eupithecia mism'ulata Grote. 



We have found the caterpillar on the cedar August 30, 1883. It pu- 

 pated September 29 to October 1, and the moth appeared May 12 of the 

 following year. 



Larva. — Body slender, sutures well marked. Head small rounded, not bilobed, not 

 so wide as the body. Uniformly pale green, being exactly concolorous with the 

 leaves. No humps or warts, the sutures marked with yellow, while the lateral 

 ridge is marked with greenish yellow, forming a prominent interrupted greenish 

 yellow lateral line. Supra-anal plate very short, smooth, obtuse at apex, the edges 

 marked with greeuish yellow. Anal legs thick and short, not broad. No dorsal 

 spines. Length 12""". 



Pupa. — Body slender, of the usual form ; green. 



4. The fir saw-fly. 

 Lophyrus ahietis Harris. 



False caterpillars closely resembling those found on the fir, and iden- 

 tical with that found on the low-bush juniper, occurred on two cedar 

 hedges in Brunswick, from July 18 to the last of August. But a few 

 scattered individuals occurred. We will give a description of the variety 

 found on the cedar. 



Body cylindrical, broadest on the thoracic segments; all the segments finely trans- 

 versely wrinkled. Head small round, deep, amber-colored ; eyes black. Body pale 

 green with a broad diffuse dark green medio-dorsal and a lateral stripe. Body paler 

 beneath. Thoracic feet black. Eight pairs of abdominal feet green. Length 13™™. 



One was found without the three dark stripes. This species differs 

 from the others in the caterpillar having no dark spots on the body as 

 seen in most Lophyrus larvae. 



5. The promethea moth. 

 Callosamia promethea (Drury). 



Said by Mr. Eiley to feed on the arbor vitse. (Fourth Rep., 123.) 



6. Ematurga faxonii Minot. 



Professor Eiley has reared this moth from caterpillars found on the 

 arbor vitae. It also occurs on the cranberry. 



7. Noctuid ? larva. 



This caterpillar was observed at St. Augustine, Anastasia Islands, 

 on the common red cedar, April 14. The specimens were probably 

 immature.
